Current projects
Transpower is undertaking a number of major projects to upgrade the National Grid – New Zealand’s high voltage electricity transmission network.
North Island Grid Upgrade Project (NIGUP)
We are building a new power link between Whakamaru and Auckland. This is one of the largest transmission projects to be undertaken in New Zealand since the 1960s.
North Auckland and Northland Grid Upgrade (NAaN) project
We are reinforcing the transmission network through Auckland and into North Auckland with new underground cables and a new transformer.
HVDC Inter-Island Link project
We are constructing and installing new AC/DC converter equipment at Benmore (South Island) and Haywards (North Island) substations to increase the capacity of the high voltage direct current (HVDC) inter-island link.
Wairakei to Whakamaru Replacement Transmission Line project
We are building a new double circuit transmission line between Wairakei and Whakamaru to help connect more generation being built in the area.
